IMPROVEMENT IN FILTERS FOR WINE.

Specification forming part of Letters Patent No. 145,288, dated December 9, 1873 application filed July 14, 1873.

To all whom it may concern:

Be it known that I, O. W. FARoIoT, of Kelleys Island, in the county of Erie and State of Ohio, have invented a new and useful Improvement in Wine-Filters; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, and being a part of this specification, in which my improvement is shown in a sectional perspective view.

In wine-filters, as heretofore constructed, a considerable percentage of wine escapes be tween the periphery of the perforated bottom which supports the filtering material and the walls of the filter-vat, thereby defeating the purpose of the filter by running wine more or less turbid.

The objects of this invention are to so construct the filter that all the wine will be compelled 'to pass through the filter; also, to so construct the false bottom that the space underneath it may be cleansed without taking out the bottom head of the filter-vat.

The invention consists in the peculiar construction of the false bottom with a sliding door in its middle to give access to the space underneath it.

In the drawing, A represents the filter-vat, built up of staves and hoops, with a head, B,

- crozed and permanently secured in its bottom,

which bottom may be bulged or convex toward the middle, to resist any pressure which it may be subjected to. In the ordinary filtervats, whosebottoms were, of necessity, so made as to be removed whenever it became necessary to cleanse them, this was not possible; hence they were extremely liable to burst under pressure. They were, for the same reason, restricted in diameter and capacity. In my filter, the bottom head being stationary, it may be so made as to resist any pressiu'e to which it naturally may be subjected; it also enables me to increase the diameter of the tub, and, consequently, to increase the capacity of the filter. U is a false bottom, crozed in the staves of the tub, and perforated with numerous small openings. At one side of its center is formed a rectangular depression, a, and adjoining a rectangular opening, b, having dovetail grooves c on three sides, in which slides a door, 0 to close the openin g, while the recess a receives it when pushed back to open the hatch. In either case the surface of the door is flush with that of the false bottom. A covering-piece, O is laid in the recess a when the door is closed, to fill up the recess to a level with the rest. No metallic fastenings are used, which would injure the wine. D, an annular wooden guard, of the section shown, accurately fitted to the walls of the tub and the surface of the false bottom, to prevent any leakage of wine between the periphery of the false bottom and the staves of the tub with a rabbet, e, which receives the periphery of the filter-cloth, (not shown,) upon which is laid the filtering material, preferably paper-pulp. E is a perforated follower, in two halves, which are laid upon the pulp. Across them is laid a press-beam, F, upon which rests the foot G of the screw H, tapped through the pressgirt I, whose ends are inserted in the stirrups I, at opposite sides of the top of the tub. When the pulp has been sufficiently compressed under the follower, the latter is held in place by the wedges f f, driven under blocks 9, screwed to the walls of the vat, and over shims h, interposed between the wedges and follower.

The filter, constructed as described, will run from ten to fourteen days without stopping, according to the cloudiness of the wine, filter ing from five thousand to six thousand gallons of wine, when it may be cleaned in a half-day by removing the pulp, opening the door in the false bottom, and cleaning the space under it, the hand and arm being introduced with whatever cleansing appliances may be found necessary, when the door is again closed, the pulp again placed in the filter ready for another run, saving much time and labor over the sys' tem heretofore found necessaryi. 0., to loosen the hoops and take out the headings.

WVhat I claim as my invention, and desire to secure by Letters Patent, is-- The false bottom 0, having the sliding door 0 covering-piece G recess a, opening I), and grooves 0, arranged substantially as and for the purpose set forth.
